Gene expression in experimentally injured and control mouse spinal cords

ABSTRACT: This laboratory works on selectins and their carbohydrate ligands in lymphocyte homing and inflammation. The lab also studies heparin-degrading endosulfatases and their roles in regulating the interactions of growth factors and morphogens with proteoglycans.

Gene expression in experimentally injured and control mouse spinal cords

Project description:This laboratory works on selectins and their carbohydrate ligands in lymphocyte homing and inflammation. The lab also studies heparin-degrading endosulfatases and their roles in regulating the interactions of growth factors and morphogens with proteoglycans. The purpose of the experiment is to examine gene expression profiles in spinal cords of injured as a function of time after a contusion injury. The tissue will be generated in the lab of Linda Noble, Professor in the Department of Neurological Surgery at UCSF who is an expert on the pathogenesis of spinal cord injury. Wild-type male C57B/6 mice (8-10 weeks of age) were used. Injuries were produced by contusion. Spinal cords from control mice (uninjured) and experimental (injured) mice were processed (4 and 7 days after injury). A 3 mm length of spinal cord (centered at the injury) and a 3 mm segment from a distant site were isolated from each animal. Tissue from 3 mice were pooled for each sample. Three replicate samples per treatment group were processed for RNA. Thus, a total of 18 RNA samples were hybridized to 18 gene chips. The analysis will determine whether specific glycosylation changes accompany spinal cord injury. Of particular interest are changes in the sulfation profile of proteoglycan GAG chains (e.g., chondroitin sulfate) and in the appearance of potential carbohydrate ligands for infiltrating leukocytes bearing L-selectin or other endogenous lectins.

Gene expression from null and doubly null mice for 2 sulfotransferases (HED-GlcNAc6ST and GlcNAc6ST-1) compared to WT

Project description:This laboratory works on selectins and their carbohydrate ligands in lymphocyte homing and inflammation. The lab also studies heparin-degrading endosulfatases and their roles in regulating the interactions of growth factors and morphogens with proteoglycans. Gene expression profiles from null and doubly null mice for 2 sulfotransferases (HED-GlcNAc6ST and GlcNAc6ST-1) will be compared to WT mice to find impact on L-selectin ligand formation in lymph nodes. RNA was isolated from the lymph nodes of the 2 types of null mice, 1 type of double null mice, and 1 of wild type mice. 3 duplicates of each strain were analyzed by gene expression profiling. We have null mice and doubly null in two sulfotransferases (HEC-GlcNAc6T and GlcNAc6ST-1) involved in L-selectin ligand formation in lymph nodes. Our functional analysis reveal partial loss (50 and 25%)of lymph node L-selectin ligands in the singly null mice and an 80%loss in the double null mice. We want to identify candidates for the protein scaffolds and underlying posttranslational modifications responsible for the residual L-selectin ligand activity in these mice. We will perform a glycochip analysis with mRNA isolated from lymph nodes of the 3 types of null mice and wild-type mice, all on the C57BL/6 background. Three duplicates from each strain are analyzed, requiring a total of 12 chips. The mice are 8-10 weeks of age and all female.

Gene expression in F9 teratocarcinoma cells

Project description:Dr. Esko's laboratory focuses on the structure, function, and biosynthesis of glycoproteins and proteoglycans. This laboratory also works on the design and synthesis of small molecule inhibitors of glycosylation. Gene expression in F9 teratocarcinoma cells: Study of the differential expression of glycosyltransferases, sulfotransferases and proteoglycan core proteins in F9 teratocarcinoma cells before and after differentiation with retinoic acid/theophylline/cAMP. Published data indicated that differentiation of the cells induces the synthesis of anticoagulant heparin-like compounds and a large increase in overall glycosaminoglycan synthesis.

Expression data from ICR mouse spinal cords - normal or injured spinal cord

Project description:LncRNAs played a crucial role in the cell growth, development and some diseases relating to central nerve system.This study suggest that with regulating the LncRNAs expression level we might design novel therapy for spinalcord injury. In this dataset, we profiled the expression pattern of LncRNAs by microarray method after spinal cord injury (SCI). Through Gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis seek LncRNAs potential function in the repair of spinal cord injury.
